wifi: at76c50x: fix use after free access in at76_disconnect



[ Upstream commit 27c7e63b3cb1a20bb78ed4a36c561ea4579fd7da ]

The memory pointed to by priv is freed at the end of at76_delete_device
function (using ieee80211_free_hw). But the code then accesses the udev
field of the freed object to put the USB device. This may also lead to a
memory leak of the usb device. Fix this by using udev from interface.
